编制了一份名为“EAGrid2000--日本”的新的大气排放清单，以便为研究2000年东亚区域、特别是日本的大气污染的远程传输提供可靠的基础数据。在编制这份清单时，以很高的时间和空间分辨率详细估计了日本区域的排放量：在时间上、按小时逐月、在空间上，纬度为30“，经度为45”，相当于大约1公里×1公里的分辨率。日本的人为年排放量估计如下：SO2，0.87Tg；NOx，2.4Tg；NMVOC，2.0Tg；NH3，0.41Tg；CO，5.4Tg；PM10，0.19Tg；PM2.5，0.15Tg；二氧化碳，1.2Pg。利用这一详细清单，可以将多种嵌套技术应用于远程传输模式模拟，以区分源自亚洲大陆的贡献和来自日本地区的本地来源。此外，根据估计，还强调了排放量变化的重要性，特别是日变化、周变化和季节变化。
A new atmospheric emissions inventory, called “EAGrid2000-Japan”, was developed to provide reliable fundamental data for studies of the long-range transport of air pollution in the East Asia region, specifically targeting Japan, in the year 2000. In the development of this inventory, emissions from the Japanese region were estimated in detail with high temporal and spatial resolution: temporally, hourly by month, and spatially, 30″in latitude and 45″in longitude, equivalent to approximately 1km×1km resolution. Anthropogenic annual emissions in Japan were estimated to be as follows: SO2, 0.87Tg; NOx, 2.4Tg; NMVOC, 2.0Tg; NH3, 0.41Tg; CO, 5.4Tg; PM10, 0.19Tg; PM2.5, 0.15Tg; and CO2, 1.2Pg. Using this detailed inventory, multiple nesting techniques can be applied to long-range transport model simulations to distinguish the contribution originating on the Asian continent from the local sources in the Japanese region. Also, the importance of emission variations, specifically diurnal, weekly and seasonal variations, was highlighted based on the estimations.
